Digi claims the ME 9210 to be “the smallest embedded device server available with Linux.” Although the company is targeting the module primarily at data acquisition and control applications — such as PLCs (programmable logic controllers), PDUs (power distribution units), and environmental control equipment — it’s completely general-purpose in function, and should prove popular in numerous other embedded devices.
The ME 9210 is based on Digi’s recently-introduced NS9210 system-on-chip, based on a 32-bit ARM926EJ-S core (with MMU) and clocked at 75 MHz. The module also integrates 8MB of RAM and up to 4MB of flash memory. Built-in interfaces include 10/100 Ethernet, a high-speed serial port, SPI and I2C serial interfaces, 10 GPIO lines, and a CAN fieldbus.

The ME 9210 module also provides advanced power management capabilities, and its support for power-over-Ethernet (PoE) enables it to be powered directly through its RJ45 Ethernet connector. It requires 3.3V DC at around 1.1W active and 0.6W standby, and it’s rated for -40 to +85 degrees C operation.
The ME 9210 is expected to begin shipping in December, priced at $48 in quantity (1,000). This includes the embedded Linux OS. A $399 quick start kit will also be available in December; it includes the ME 9210 module, a development board, documentation, a DVD containing the Linux OS and Eclipse-based tools, and a power supply.
